This invention relates to mechanism for winding-down or drawing-oil fabric as it is produced on knitting machines, more especially circular knitting machines.

The invention is intended for application mainly to :circular knitting machines of the rotary needle cylinder type, but it may also be applied to circular knitting machines of the stationary needle cylinder type.

Moreover, the invention. concerns fabric winding-down or drawing-off mechanism of the kind which includes a pair of geared rollers one or each of which is suitably pressed towards the other, e. g. by spring means, and in which the fabricis gripped between the rollers while the latter are rotated, usually in an intermittent manner, by suitable driving means, for drawing 01f the fabric as itis produced by the needles. In mechanism of this kind the rollers are geared means, sometimes in the form of cam actuated pawl and ratchet mechanism, are associated with one of the'rollers. The construction is such, moreover, that one or each of the rollers is yieldably mounted so as to permit of separation of the rollers to allow for differences in the thickness of the fabric produced on the machine.

As applied to a circular knitting machine of the rotary needle cylinder type the windingdown or drawing-off mechanism revolves bodily in unison with the needle cylinder or cylinders while the rollers are turned on the axes thereof but in a machine of the stationary needle cylinder type the winding-down or drawing-off mechanism also remains stationary while the rollers are driven. v

Now a difliculty commonly experienced with known forms of winding-down or drawing-cit mechanism is that under certain conditions the gears tend to jam or bind or to be otherwise caused to mesh improperly or, in some instances, to be taken entirely out of mesh.

With a view to overcoming this difiiculty it has heretofore been proposed to employ gearshaving extra long teeth, i. e. so-called'mangle gears, but such gears are not satisfactory for reasons well known to those acquainted with the art concerned. The object of the present invention is to provide an improved form of fabric.

winding-down or drawing-01f mechanism'of the kind herein referred to, the construction of which .is such as to enable ordinary standard machine cut gears to be used without the disadvantages aforesaid, thereby reducing the cost of producing the mechanism and providing a smooth winding-down or drawing-01f action.

In the accompanying drawings, I a Figure 1 is a plan View partly in section, of

a winding-down or drawing-01f mechanism in-- corporating the invention;

Figure 2 is a part sectional elevational view ner in which the improved mechanism operates to overcome the difiiculty'herein alluded to.

Like parts are designated by similar reference characters throughout the drawings.

For convenience in the following further description the invention; will be regarded as appliedas is mainly the intention-to a fabric winding-down mechanism having" only one yieldably mounted roller, although, as will be understood, it may be applied to a mechanism in which both of the rollers are yieldably mount- The mechanism shown in the drawings is generally of known form and comprises a pair of gear driven rollers I and 2 rotatably mounted side by side in a pair of oppositely formed brackets 3 and 4 provided one at each side of a ringlike or a circular part such .as 5 which serves to carry the rollers. .One of the rollers, i. e. the roller l, is mounted in fixed bearings 6 (Figure 1), whilst the other roller 2 has a bearing in slidable bearings or slipper blocks 1 suitably arranged in the brackets 3 and 4. springs 8 are provided for action upon the said slidable bearing or slipper blocks to press the rollers l and 2 together. Thus one of the rollers, that is to say the roller 2 is yieldably mounted to permit the rollers to separate. The roller I is-adapted at one end to be driven by pawl and ratchet mechanism hereinafter to be described, and at their ends remote from the driving means the rollers are geared together by a pair of standard machine cut spur gears 9 and 10 so that the drive is positively transmitted from" the spring-loaded roller 2 are somewhat simi- Compression larly reduced as at I2 and adapted for engagement with the blocks I. These blocks are adapted to be positioned and to slide between suitable guideways I3 formed in the brackets 3 and 4 and each block has formed therein a hole I4 (see Figure 1) for accommodation of one end of the associated compression spring 8, the other end of which latter bears against a collar I5 pro vided on an adjustment screw I6. The screws I6 are supported in bosses I I formed on plates I8 which are secured to the: aforesaid brackets by means of screws I 9. Thus, by appropriate manipulation of the adjustment screws I6, the effective strength of the springs 8 can be varied as required. Lock nuts 26 are provided on the screws Hi to lock the latter in their adjusted positions. The brackets 3 and 4 consist of appropriately shaped castings which are screwed or otherwise rigidly attached to the top of the ring-like support 5.

The gear 9 associated with the driven roller I is rigidly secured by means of a dowel pin 2I to the spindle of the said roller" and is disposed on the outside of the bracket 4. In accordance with the characteristic feature of the present invention, the other gear I0 is mounted independently of and connected to the spring-loaded roller 2 in the manner now to be described. As shown more clearly in Figure 1, the said gear is furnished with a boss Illa adapted to have a bearing in a portion 22a of a bracket or like support 22 which is made separately from but is removably attached to the roller supporting bracket 4', for

example by means of one or more screws 23 (Figure 4). The bracket 22 is extended so as to have a portion 221) which surrounds the gear 9. In this respect, therefore, the bracket 22 may be said not only to constitute a housing in which the gear I6 is rotatably mounted but also a casing for the gear 9. A cover plate 24 is attached to the outside of the bracket 22 by means of screws such as the screw 25; for the sake of clarity in Figure 4 the said cover plate has been omitted. The separately mounted gear I0 isappropriately positioned to mesh with the gearil and is formed with an axial bore 26 of adiameter sufficient to accommodate one end of a coupling rod 21'. When the various parts of the mechanism have been assembled the rod 27 extends from the interior of the separately mounted gear I0 into the spring-loaded roller 2- which is made hollow as at 28 for the purpose. It is convenient to mention here that the hollow bore 28 extends also through the reduced end I2 of the roller 2, which end projects into and works within a suitable slot or opening 29 in the roller sup-- porting bracket 4. At its inner end 21a the coupling rod 27 is ball shaped (see more particularly Figure 5) and adapted for engagement with a pin 30 which passes through a hole, or, as

shown, through an open-ended slot 21b formed in the ball and extends at right angles tothe axis of the spring-loaded roller 2, midway between the ends of the latter. This pin has a screw-threaded engagement with the roller as indicated at 3| although it may be secured in the roller in any other suitable manner. The opposite ends of the slot Z'Ib in the ball Z'Ia are suitably enlarged, e. g.

flared slightly in the manner indicated at 32 in Figure l, to enable the roller 2 and the coupling rod 27 more readily to assume different angular positions relatively to each other. In any event the slot or opening in the ball-shaped end 21a is made sufiiciently large to permit of freedom of movement within limits of the pin 30 within the said end. The construction is, in effect, such that the inner end of the coupling rod is connected to the roller 2 midway between its ends. At its opposite end the coupling rod is similarly shaped in the form of a ball 210 through which passes another pin 33 screwedor otherwise'suitably secured in the separately mounted gear III and extending at right angles both to the pin 30 and to the axis of the said gear. The end 210 passes through the slot oropening 29 and is formed with an open-ended slot 21d to receive the pin 33. By providing slots in the coupling rod the assembly of the mechanism is thereby facilitated. Although in the example illustrated the pins 30 and 3.3.and the corresponding slots in the coupling rod extend at right angles to each other, this=particular disposition of the said pins and slots is not essential. For instance, the required movements of the roller 2 and the coupling rod relatively to each other may be obtained even though the pins and slots are arranged parallel to each other in the same plane, providing, of course, that the slots are of sufficiently large dimensions to permit of the requisite freedom of movement of the pinv 30 within the ball-shaped end 21a and of the end 210 about the pin 33.

The construction so far described is therefore such that when the rollers are driven, the coupling rod 21 rotates together with the springloaded roller 2 and the associated gear I0 and thereby serves to transmit the drive from the latter to the said roller; When the rollers are separated the coupling rod turns about the pin 33 in the gear II! and at such times as the springloaded roller 2 assumes an angular position as aforesaid the pin 30 turnsin the ball-shaped end 21a of the rod.

In Figures 1 to 4 the mechanism is shown with the rollers I and 2' pressed firmly together by means of the springs 8. The manner in which the spring-loaded roller 2'moves relatively to the companion roller I without affecting the gears is, however. shown diagrammatically in Figure 6. As will be seen, the roller 2 is not only separated from the roller I but has assumed an angular position relatively to the latter. In these circumstances the gears 9 and I 0 remain properlly in mesh and the roller 2 is driven from the gear Iii through the coupling rod 27. During movement of the roller 2 into such a position as that shown the pin 30 turns in the end 21a of the coupling rod, whilst the end 210 of the latter moves within the gear I0. In this way the roller 2 is enabled to move independently of the gear Ill without interrupting the drive.

The winding-down or drawing-off mechanism herein described with reference to the drawings revolves bodily in unison with the needle cylinder or cylinders of" the machine to which the mechanism is applied at the same time as the rollers I and 2 are being intermittently rotated (in the manner hereinafter to be described). In this connection the ring-like part 5 aforesaid is adapted to be driven in suitable timed relation with the rotational motion of the said cylinder or cylinders, for which purpose it is conveniently supported in a bracket 34 and formed with a depending flange 35 to which is rigidly attached a gear wheel 3.6 adapted tomesh with a pinion 3! in turn driven from any suitable part, e. g. the main shaft of the machine. For instance, if, as is mainly the intention, the improved mechanism is applied to a knitting machine of the type having superposed needle cylinders, then the pinion 31 maybe driven from the main shaft of the machine, that is to say from the same shaft as that from which the needle cylinders are driven. -In one specific arrangement a vertical shaft or spindle 38 (see Figure 1) is driven from the main shaft (not shown), for example through bevel gearing, and has rigidly secured to the lower end thereof a gearwheel 39 adapted to mesh'with the pinion 31. In this way the ringlike part 5, together with all that it carries, is

rotated continuously and in unison with the needle cylinders.

A drum or cannister 40 for reception of the knitted fabric as it is drawn ofi from the needles of the machine is also secured to the depending flange 35. For this purpose the drum or cannister is conveniently provided at the top with an upwardly extending circular flange '4! which is arranged to surround the flange 35 and is rigidly secured to the latter by means of screws 42. Thus the ring-like part 5, the gear whee1 36 and the drum or cannister 40 in effect constitute a single, bodily rotatable unit.

' The bracket 34 is mainly of circular form and has formed integrally therewith a horizontally disposed annular flange 34a which is disposed within the bracket and constitutes a supporting ledge for the ring-like part 5. .Lugs or similar portions such as, 34b are conveniently formed on thebracket to enable it to be readily secured in position on a convenient part of or on the machine frame 43 (Figure 1). v

The roller l is adapted to be driven in an intermittent manner by any suitable driving means. In the specific example illustrated, however, the said roller is driven by a generally known form of cam actuated pawland ratchet mechanism, the driving means being associated with the end of the roller remote from the gear 9. As will be seen, a ratchet wheel 44 formed with teeth of relatively fine pitch is rigidly secured to the spindle of the roller 1 and disposed on the outside of and adjacent to the roller supporting bracket 3. In association with said ratchet wheel there is provided a springcontrolled pawl 45 which is pivotally mounted upon an arm 46. In turn this arm is pivotally mounted at 41 upon a part of or on or adjacent to the bracket 3 and is conveniently controlled by a tension spring 48. The said spring is connected at one end to a peg or projection 49 extending laterally from the bracket 3 and at the other end is anchored to a lug or extension 50 formed on the arm 46. On that side of the pivot 4'! remote from the spring 48 the aforesaid arm is formed with an appropriately shaped extension 51 which carries a roller 52 for action upon the upper edge of a circular flanged portion 340 of the bracket 34. This flanged portion is appropriately formed so as to constitute a cam ring which is presented to the roller 52 during bodily rotation of the winding-down or drawing-01f mechanism. The construction is consequently such that as the mechanism rotates bodily the roller 52 is acted upon at appropriate times by the cam ring to turn the arm 46 on its pivot against the action of the spring 48 and thereby impart operative strokes to the pawl 45 and rotate the ratchet wheel 44.

and hence also the roller l intermittently in a clock-wise direction as viewed in Figure 3. Immediately after each turning movement of the arm 46 in the manner just described, it returns to its normal position under the spring action, thereby imparting a' reverse or idle stroke to the pawl. A spring-controlled back stop pawl or detent 53, which is conveniently mounted upon a pivot pin 54 carried by the roller supporting bracket 3, is provided in association with the ratchet wheel to prevent backward rotation of the latter during reverse or idle strokes of the pawl 45. Movement of the arm 46 under the action of the spring 48 is limited by an abutment screw 55 (see Figure 3) which is carried by the extension and adapted forcontact with thering-like part 5; on the other hand movement of the said arm in the opposite direction, i. e. against the spring action, is determined by an abutment screw 56 whichis carried by the lug or extension 50 and similarly adapted for contact with the ring-like part 5. Thus by appropriate adjustment of the screws 55 and 56 the stroke of thepawl 45 can be varied. This provision for adjustment, in addition to the adoption of a ratchet wheel having fine teeth, enables the setting of the mechanism to be varied so that the rollers I and 2 will be driven at one of a fairly wide range of different speeds, according to requirements.

As shown more clearly in Figure 2, the cam ring 340 is inclined in such a way that the ratchet wheel is racked on one step for each complete revolution of the ring-like part 5. If desired, however, the contour of the cam ring may be such that the ratchet wheel isgracked on two or even more steps per revolution of the said part.

' The improved mechanism is such as to enable the gears to mesh in a proper manner irrespective of the various parallel and angular positions assumed by the yieldably mounted roller with respect tothe companion roller during passage of fabric between the rollers. In this Way the yieldably mounted roller can readily adapt itself to different thicknesses of fabric such, for example, as heel and toe pouches in hosiery, and assume an angular position, for instance when the fabric moves to one end of the rollers, without in any way adversely affecting the operation of the mechanism and thereby enabling the fabric to be drawn off in a steady manner.

The improved winding-down or drawing-off mechanism is applicable to knitting machinesmore especially circular knitting machines-in general for producing fabric in continuous lengths, and to similar machines for producing garment lengths or portions separately, but is applicable more particularly to machines for producing seamless hosiery, the dimensions of the mechanism being varied according to requirements.
